Abstract

The invention provides a coke oven coking end monitoring system, which comprises a waste gas temperature detecting device (1) and a data collecting and controlling device (2), wherein the waste gas temperature detecting device (1) comprises a group of thermocouples (11) and a group of high-temperature-resistant compensation conduction wires (12), the thermocouples (11) are arranged at the tee position for connecting the riser tube and the bridge tube of a coke oven carbonization chamber, the high-temperature-resistant compensation conduction wires are arranged near the thermocouples (11), andthe data collecting and controlling device (2) comprises a data collecting and processing module (21) and a data storage module (22). According to the present invention, the waste gas temperature is detected, the coking end time is determined by using the waste gas temperature change, and the coking end time, the placing time and the coking time are calculated by using the coking end time, such that the fine-tune and the accurate adjustment of the coke oven heating system can be guided, the visual pollution can be reduced, the energy can be saved, and the coke quality can be ensured.

Description

technical field [0001] The invention belongs to the field of coking equipment, in particular to a coke oven flame fall monitoring system. Background technique [0002] The heating of the coke oven adopts the thermal process of temperature management, that is, by measuring the temperature of the center of the coke cake after dry distillation to 1000±50°C, a certain quality (physical and chemical indicators of coal blending), quantity (coal loading of each hole in the carbonization chamber) is determined. Amount) of mixed coal within a specified coking time to heat the heat required for carbonization to adjust the heating system, mainly including the temperature system, pressure system and the supply of gas flow and air volume. Since the relevant heating parameters and adjustments are mainly aimed at the entire coke oven, there are always fluctuations and adjustments in the production order during the coking production process, and it is difficult to obtain the differences bet...
